ABOUT INDIAN OIL

y Indian Oil Corporation Limited, or Indian Oil, is an Indian state ownedoil and gas company headquartered at Mumbai, India.

y It is only indian company in FORTUNEs global 500 list, ranked 125 in

2010.y Indian Oil and its subsidiaries account for a 46% share in the

petroleum products market, 34.8% share in refining capacity and 67%downstream sector pipelines capacity in India.

y It has also started Auto LPG Dispensing Stations (ALDS). It supplies

Indane cooking gas to over 47.5 million households through a networkof 4,990 Indian distributors.

y It owns and operates the countrys largest network of cross-countrycrude and product pipelines, with a combined length of 7,730 km witha combined capacity of 56.85MMTPA.

BARAUNI REFINERY

y Barauni Refinery was built in collaboration with Russiaand Romania IN 1964.

y

The refinery receives crude oil by pipeline from Paradip onthe east coast via Haldia.

y Its capacity is 6 MMTPA.

ATMOSPHERIC AND VACCUM DISTILLATION

UNIT

y The ADU (Atmospheric Distillation Unit) separates most of the lighterend products such as gas, gasoline, naphtha, kerosene, and gas oil fromthe crude oil.

y The bottoms of the ADU are then sent to the VDU (VacuumDistillation Unit).

FLUID CATALYTIC CRACKING UNIT

y In the newer designs for Fluid Catalytic Cracking Unit, cracking takesplace using a very active zeolite-based catalyst in a short-contact timevertical or upward sloped pipe called the "riser.

y The ho t catalyst vapourizes the feed and catalyzes the crackingreactions that break down the high molecular weight oil into lightercomponents including LPG, gasoline, and diesel.

y The present processing capacity of the unit is about 1.48 MMT/Yr.

DIESEL HYDRO DESULPHURIZATION UNIT

y DHDS (Diesel hydro desulphurization unit) is set up for thefollowingpurposes:

1. A step towards pollution control.

2. To produce low sulphur diesel (0.25 w/w %) as per govt. directivew.e.f. Oct. 1990.

y The Hydrodesulphurization reaction releases H2S in gaseoushydrocarboneffluents. This H2S removal is achieved by means of a

continuous absorptionprocess using a 25% wt. DEA solution.


13/27

SULPHUR RECOVERY UNITy The unit consists of three identical units A, B and C. One of them is

kept standby.

y The process design is in accordance with common practice to recover

elemental sulfur known as the Clause process, which is furtherimproved by Super Clause.

y Each unit consists of a thermal stage, inwhich H2S is partially burnt

with air, followed by two catalytic stagesse process.y Acatalytic incinerator for incineration of all gases has been

incorporated inorder to prevent pollution of the atmosphere.

BOILERy Types

1. Water tube boiler

2. Fire tube boiler

Barauni refinery uses 4 Russian made water tube boiler.


17/27

WORKING CONDITIONy Nominal steam generating capacity 75 tons/hr.

y Superheated steam temperature 440 degree celsius.

y

Feed water temperature 145 degree celsius.


18/27

SUPERHEATERy A superheater is a device used to convert saturated steam or wet steam

into dry steam used for power generation or processes.


19/27

Turbiney There are 5 turbines in TPS . Three steam turbine and two

gas turbine.

y

A steam turbine is a mechanical device thatextracts thermal energy from pressurized steam , andconverts it into rotary motion.

y A gas turbine, also called a combustion turbine, is a typeof internal combustion engine . It has an upstream

rotating compressor coupled to a downstream turbine , anda combustion chamber in-between.

DEAERATORA deaerator is a device that is widely used for the removalof air and other dissolved gases from the feedwater tosteam-generating boilers.


22/27

DEMINERALLISATION PLANTy Demineralisation is the process of removing the mineral salts

from water by ion-exchange. Impurities that remains dissolvedin water dissociate to form positive and negative charged

particles known as ions. These impurities or compounds arecalled electrolytes. Generally, all natural water has electrolytes in

varying concentrations. An ion-exchange vessel holds ion-exchange resin of the required type through which water isallowed to pass. The selective ions in the water are exchanged

with ions or radicals loosely held by the resin. In this way, thewater is passed through several vessels or a mixed bed vessel sothat both positive and negative ions are removed and water isdemineralised.

EQIPMENTSy HEAT EXCHANGER

y PUMP


25/27

HEAT EXCHANGERy A heat exchanger is a piece of equipment built for efficient

heat transfer from one medium to another.

y

Shell and tube heat exchanger is used in barauni refinery.


26/27

PUMPy A pump is a device used to move fluids, such as liquids

, gases or slurries.

y

A centrifugal pump is a rotodynamic pump that uses arotating impeller to create flow by the addition of energy toa fluid.
